음성신호를 기록해서 되는 기록매체를 기록시되는 역방향으로 주사해서 얻어지는 재생 음성신호를 메모리에 기억하고, 이 메모리에서 기억시와는 역방향으로 재생 음성신호를 소정 속도로 독출하는 음성 재생장치에 있어서, 상기 기록 매체를 기록시의 약 N(단 N은 자연수)배의 소도로 역방향 재생하는 재생수단, 재생 음성신호를 재생 상대속도에 비례하는 속도로 AD 변환하는 AD 변환수단, 이 AD 변환 데이타를 서입 어드레스에 따라서 서입하면서 독출 어드레스에 따라서 독출하는 메모리, 독출 어드레스에 따라서 일정한 속도로 독출하는 AD 변환 데이타를 DA 변환하는 DA 변환수단, 및 상기 AD 변환 데이타를 독출하기 위해 한 방향으로 변화하는 독출 어드레스를 상기 메모리에 공급함과 동시에, 상기 독출 어드레스의 N배 속도로 변환하는 어드레스 정보를 상기 독출 어드레스의 일순회 주기의 N/(N+1)배의 주기로 또한 이 일순회 주기의 1/(N+1)기간에만 서입 어드레스로서 상기 메모리에 공급하는 어드레스 발생수단을 각각 구비하고 있는 것을 특징으로 하는 역전 음성 재생회로.In a voice reproducing apparatus, a reproducing audio signal obtained by scanning a recording medium for recording audio signals in a reverse direction at the time of recording is stored in a memory, and the reproducing audio signal is read out at a predetermined speed in a reverse direction from the memory. Playback means for reverse-reproducing the recording medium at about N times (where N is a natural number), AD conversion means for AD conversion of a reproduced audio signal at a rate proportional to a reproduction relative speed, and the AD conversion data. A memory which reads in accordance with a write address and reads in accordance with a read address, DA converting means for DA converting AD converted data read at a constant speed according to the read address, and changes in one direction to read the AD converted data. Address information for supplying a read address to the memory and converting at a rate N times the read address. Are each provided with address generating means for supplying to the memory as a write address in a period of N / (N + 1) times the one-time period of the read address and only in the 1 / (N + 1) period of this one-time period. Inverted voice reproduction circuit, characterized in that. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
